The reference to applied charge voltage keeps coming into this discussion, with point being batteries charging at 13.x volts not 14v
And that amperage is lower when battery voyage is up
Well !!!
Most of us with solar arrays also have inverters
Some large some small, I have two connected and operating 24/7 and a spare, just in case something happens
Now what do you suppose the output of your solar array is going to be at or near STC when you use that inverter at lunch or brunch
Maybe your camped and the panels are tilted and you just decided to warm up a cup of coffee or makes hot water for soup or tea
Yeah full voltage full amps yield.. Maybe only for a few minutes, and battery voltage will drop but solar input will be max
Do you want 22 amps from your 30 amp controller, are you going to Add another panel to get 30 amps
Maybe you have a 20 amp controller and 200w aka 13 amps, going to buy a 30 amp controller when you add another panel ?, just so you can get 20 amps charge
Yeah I'm flogging the dead horse...I want to get the mental gears turning
We have talked wire size to death and beyond,
But our discussion of controllers has been centered around MPPT vs PWM..
Not quality real world ratings and programming features
